request delaying function
A/D converter start request
delaying function
[1] Set the cycle in the timer A/D converter start request cycle
buffer register (TADCOBRA_4 or TADCOBRB_4) and timer
A/D converter start request cycle register (TADCORA_4 or
TADCORB_4). (The same initial value must be specified in
the cycle buffer register and cycle register.)
[2] Use bits BF1 and BF2 in the timer A/D converter start
request control register (TADCR) to specify the timing of
transfer from the timer A/D converter start request cycle
buffer register to A/D converter start request cycle register.
• Specify whether to link with interrupt skipping through bits
ITA3AE, ITA4VE, ITB3AE, and ITB4VE.
• Use bits TU4AE, DT4AE, UT4BE, and DT4BE to enable
A/D conversion start requests (TRG4AN or TRG4BN).
Notes: 1. Perform TADCR setting while TCNT_4 is stopped.
2. Do not set BF1 to 1 when complementary PWM mode
is not selected.
3. Do not set ITA3AE, ITA4VE, ITB3AE, ITB4VE,
DT4AE, or DT4BE to 1 when complementary PWM
mode is not selected.
